We look at the division of 381817 by 67 
The aim is to understand the frequency of 67 in 381817.

Let's proceed to step 1:
When dividing 3 by 67, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 67

Going ahead to step 2:
The number 67 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 67

On to step 3:
The number 67 fits into 381 5 times, leaving a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 335 from 381, we get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 67

Step 4:
When dividing 468 by 67, we get 6 with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 56.0
The remainder is 66 after subtracting 402 from 468.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 67

On to step 5:
When dividing 661 by 67, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 569.0
The remainder is 58 after subtracting 603 from 661.
Append the next digit (7) from the dividend to 58 and continue with: 587 / 67

Going ahead to step 6:
The number 67 fits into 587 8 times, leaving a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 5698.0
The remainder is 51 after subtracting 536 from 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
If we divide 510 by 67, we get 7 and a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 5698.7
If we subtract 469 from 510, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 8:
If we divide 410 by 67, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 5698.76
Subtract 402 from 410 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 67, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 5698.761
Subtract 67 from 80 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
67 goes into 130 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 5698.7611
Deduct 67 from 130 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

After the division, we end up with 5698.7611 and a remainder of 0.00063.
